Ingredients
For this simple chicken recipe, you'll need:
4 boneless, skinless chicken breasts
1 packet dry onion soup mix
1 cup sour cream
For best results, choose chicken breasts that are similar in size so they cook evenly.
Although these are the three ingredients that make up the dish, you can optionally use a small amount of cooking spray or oil to prepare the baking dish.
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C).
Allow the oven to fully preheat while you prepare the chicken. Starting with a properly heated oven helps the chicken cook more evenly from the beginning.
Lightly grease a baking dish large enough to hold the chicken breasts in a single layer.
Step 2: Prepare the Chicken
Pat the chicken breasts dry with paper towels.
This small step is useful because removing excess moisture helps the creamy onion mixture adhere better to the chicken.
If your chicken breasts are particularly thick, you can gently pound them to a more even thickness. This isn't absolutely necessary, but it can help the chicken cook more evenly and prevent thinner portions from becoming overcooked before the thickest part is done.
Place the chicken breasts in the prepared baking dish.
Step 3: Make the Onion Mixture
Add the sour cream to a medium bowl.
Pour in the dry onion soup mix.
Using a spoon or spatula, stir until the seasoning is evenly incorporated into the sour cream.
The mixture should become thick, creamy, and speckled with the dried onion and seasoning.
This simple mixture acts as both the seasoning and the sauce for the chicken.
Step 4: Coat the Chicken
Spoon the onion mixture over the chicken breasts.
Use the back of a spoon or a spatula to spread it evenly across the top of each piece.
Try to cover the chicken from edge to edge. The creamy mixture will slowly melt and spread as the chicken cooks, allowing the onion seasoning to flavor the meat.
There is no need to add additional salt because onion soup mix is already highly seasoned.
